MACROMEDIA FLASH MX 2004-USING COMPONENTS Use Manual page 469

The second usage example uses a dispatcher/listener event model. A component instance
( ) dispatches an event (in this case,
listInstance
function, also called a handler, on a listener object (
a method with the same name as the event on the listener object; the method is called when the
event is triggered. When the event is triggered, it automatically passes an event object
( ) to the listener object method. Each event object has properties that contain
eventObject
information about the event. You can use these properties to write code that handles the event.
Finally, you call the
instance that broadcasts the event to register the listener with the instance. When the instance
dispatches the event, the listener is called.

Example
